DETAILED DESCRIPTION
[0016] Hereinbelow, a description will be given of an X-ray
diagnostic system and a medical image diagnostic system according
to embodiments of the present invention with reference to the
drawings.
[0017] According to one embodiment, an X-ray diagnostic system is
used with an operation apparatus for operating, from a position
separated from an object, a device inserted inside the object, and
includes an imaging apparatus, a designation receiving circuit, a
first display, and a second display. The imaging apparatus performs
X-ray imaging of the object. The designation receiving circuit
receives designation of a position on medical data from a first
user who operates the device. The first display is disposed at a
position visible from the first user, and displays a first image
according to the designation of the position. The second display is
disposed at a position visible from a second user who performs
positioning of the imaging apparatus, and displays a second image
different from the first image according to the designation of the
position.
[0018] FIG. 1 is a block diagram illustrating a medical image
diagnostic system 10 including an X-ray diagnostic system 1
according to one embodiment of the present invention.
[0019] The X-ray diagnostic apparatus 11 is configured as, for
example, an angiography apparatus, and includes an imaging
apparatus 12 and an image processing apparatus 20 as shown in FIG.
1. The imaging apparatus 12 of the X-ray diagnostic apparatus 11 is
generally installed on an inspection room, and is configured to
generate X-ray projection data of an object P. The image processing
apparatus 20 is, e.g., installed on an operators room adjacent to
the inspection room, and is configured to generate X-ray images
based on X-ray projection data and cause a display to display the
generated X-ray images. Note that the image processing apparatus 20
may be installed on the inspection room where the imaging apparatus
12 is installed. In the present embodiment, the image processing
apparatus 20 operates not according to operations performed by an
operator O as a first user but according to operations performed by
a medical engineer M in the inspection room as a second user.
[0020] The medical image diagnostic system 10 includes a remote
catheter 30 and a remote console 40 in addition to the X-ray
diagnostic apparatus 11. The remote catheter 30 and the remote
console 40 constitute a so-called remote catheter system. In the
present embodiment, the operator O who remotely controls a device
32 inserted inside the object P by operating the remote console 40
is a user except the medical engineer M.
[0021] The X-ray diagnostic system 1 includes a display disposed at
a position visible from the operator O and a designation receiving
circuit configured to receive designation for operations with
respect to a remote catheter 30, in addition to the X-ray
diagnostic apparatus 11. The device 32 of the remote catheter 30
which is inserted inside the object P to be imaged by the X-ray
diagnostic apparatus 11 of the X-ray diagnostic system 1 is
operated from a position remote from the object P. The designation
receiving circuit is realized as, e.g., a remote input circuit 43
of the remote console 40. Additionally, the display disposed at a
position visible from the operator O is realized as, e.g., a
display 71 of the image processing apparatus 20 and/or a display of
a display input circuit 41 or 42 of the remote console 40.
[0022] The imaging apparatus 12 of the X-ray diagnostic apparatus
11 includes an X-ray detector 13, an X-ray source 14, a C-arm 15, a
bed 16, a tabletop 17 of the bed 16, a display 18, and an
inspection room console 19.
[0023] The X-ray detector 13 is provided at one end of the C-arm 15
so as to be opposed to the X-ray source 14 with the object P
supported by the tabletop (for example, a catheter table, etc.) 17
of the bed 16 being interposed therebetween. The X-ray detector 13,
which is made up of a flat plane detector (FPD), detects X-rays
which are radiated to the X-ray detector 13 passing through the
object P, and outputs projection data of X-ray based on the
detected X-rays. This projection data is provided to the image
processing apparatus 20 via the inspection room console 19. Note
that the X-ray detector 13 may include an image intensifier, a TV
camera, or the like.
[0024] The X-ray source 14 is provided on the other end of the
C-arm 15, and includes an X-ray bulb and an X-ray aperture. The
X-ray aperture is an X-ray irradiation field aperture configured
of, e.g., plural lead blades. The X-ray aperture adjusts an X-ray
irradiation range radiated from the X-ray bulb under the control of
the inspection room console 19.
[0025] The C-arm 15 integrally holds the X-ray detector 13 and the
X-ray source 14. When the C-arm 15 is controlled by the inspection
room console 19 and driven, the X-ray detector 13 and the X-ray
source 14 are integrally moved around the object P. The X-ray
detector 13, the X-ray source 14, and the C-arm 15 constitute an
imaging system for performing X-ray imaging of the object P.
[0026] The X-ray imaging by the imaging system includes so-called
fluoroscopy and radiography. Fluoroscopy is X-ray imaging to
acquire an image by X-ray irradiation with a weaker X-ray
irradiation intensity compared with radiography. For that reason,
although the resolution of a fluoroscopic image acquired by
fluoroscopy is lower than that of a radiographic image acquired by
radiography, X-ray dose to which the object P is exposed in
fluoroscopy is lower than in radiography. Therefore, fluoroscopy is
suitable when it is desirable to confirm an X-ray image of the
object P in an animating manner in real time. On the other hand,
although X-ray dose to which the object P is exposed is higher, the
image quality is clearer in radiography than in fluoroscopy. In the
following description, fluoroscopy and radiography are conveniently
referred to as X-ray imaging, and an X-ray fluoroscopic image and
an X-ray radiographic image based on X-ray imaging are conveniently
referred to as an X-ray image.
[0027] Moreover, when the X-ray diagnostic apparatus 11 is used as
an angiography apparatus, the X-ray diagnostic apparatus 11 may be
of a biplane type having two lines of imaging system which is made
up of the X-ray detector 13, the X-ray source 14, and the C-arm 15
and captures an X-ray image of the object P. In the case of biplane
type, the X-ray diagnostic apparatus 11 can acquire a biplane image
(F (frontal) side image and L (lateral) side image) by causing an
X-ray beam to be radiated separately from each of two directions of
the F side having a floor mounted C-arm and the L side having a
ceiling travelling Q-arm.
[0028] The bed 16 is installed on a floor surface and equipped with
the tabletop 17 for placing the object P. The bed 16 moves the
tabletop 17 in a horizontal direction and in a vertical direction
and rotates the tabletop 17 under the control of the inspection
room console 19.
[0029] The display 18 has one or plural display regions, and
displays various types of information such as a provisional image
for positioning (hereinafter, referred to as a positioning
provisional images) and a fluoroscopic image being updated on a
real-time basis under the control of the inspection room console
19. The display 18 is configured of a general display output device
such as a liquid-crystal display, an OLED (Organic Light Emitting
Diode) display.
[0030] The inspection room console 19 is controlled by the image
processing apparatus 20, and controls the X-ray detector 13 so as
to perform X-ray imaging of the object P and generate projection
data. The inspection room console 19 outputs the projection data to
the image processing apparatus 20. The inspection room console 19
is controlled by the image processing apparatus 20 and generates,
e.g., projection data before and after administration of a contrast
medium so as to output the generated projection data to the image
processing apparatus 20. For instance, the inspection room console
19 may be a satellite console configured to be capable of freely
moving on the floor of the inspection room.
[0031] When the X-ray diagnostic apparatus 11 is configured so as
to be capable of rotation DSA (Digital Subtraction Angiography)
imaging, the inspection room console 19 performs the rotation DSA
imaging so as to generate projection data before and after
administration of a contrast medium and output the generated
projection data to the image processing apparatus 20, under the
control of the image processing apparatus 20. In the case of the
rotation DSA imaging, image data before administration of the
contrast medium (i.e., mask image data) and image data after the
administration of the contrast medium (i.e., contrast image data)
are generated with respect to the same portion of the same object
P. When the rotation DSA imaging is practicable, the X-ray
diagnostic apparatus 11 can also acquire a three-dimensional blood
vessel image on the basis of the mask image data and the contrast
image data acquired by the rotation DSA imaging.
[0032] The inspection room console 19 includes at least a processor
and memory circuitry. The inspection room console 19 is controlled
by the image processing apparatus 20 according to programs stored
in this memory circuitry so as to perform X-ray imaging such as
fluoroscopy of the object P by controlling the imaging system and
output the projection data.
[0033] Although FIG. 1 illustrates a case where the inspection room
console 19 and the image processing apparatus 20 are connected with
each other by wire, the inspection room console 19 and the image
processing apparatus 20 may be connected with each other so as to
be capable of data transmission/reception via a network.
[0034] Additionally, the X-ray diagnostic apparatus 11 may include
a non-illustrated injector. In this case, the injector injects a
contrast medium through the device 32 of the remote catheter 30
having been inserted into an affected area of the object P under
the control of the inspection room console 19. The timings of
injection and stopping of the contrast medium, and the density and
injection rate of the contrast medium are automatically controlled
by the inspection room console 19. Moreover, the present embodiment
is not limited to causing the injector to operate under the control
of the inspection room console 19. For instance, an instruction by
the medical engineer M may be received via an input unit installed
on the injector such that the contrast medium is injected at a
concentration, at a speed, and at timing according to this
instruction. Similarly, an instruction by the operator O may be
received via the remote console 40 such that the contrast medium is
injected at a concentration, at a speed, and at timing according to
this instruction.
[0035] The remote catheter 30 of the remote catheter system as an
example of a remote control system includes a robot arm 31 and the
device 32, and is configured to insert the device 32 into a
predetermined portion (e.g., an affected area) of the object P
under the control of the remote console 40. Additionally, the
remote catheter 30 may be configured to be capable of remote
controlling plural devices 32.
[0036] The X-ray diagnostic apparatus 11 of the present embodiment
assists the medical engineer M in adjusting an imaging region and
an imaging direction such that images desired by the operator O of
the device 32 are acquired, and this assistance method will be
briefly described.
[0037] As to operations of the imaging apparatus 12, various
operations such as movement of the imaging system, movement of the
bed and its tabletop 17, X-ray imaging performed by the imaging
system, and administration of a contrast medium controlled by the
non-illustrate injector are included. However, it is difficult for
the operator O of the device 32 to confirm the current conditions
around the imaging apparatus 12 in detail. This is because the
operator O is at a position remote from the inspection room or
sight of the operator O is blocked by a protection board of the
remote console 40 even if the remote console 40 is installed in the
inspection room. Thus, if the operator O remotely controls the
imaging apparatus 12, it is difficult for the operator O to
accurately recognize positional relationship between operation
targets of the remote control and obstacles in the vicinity of
those operation targets (e.g., mechanical component of the imaging
apparatus 12 and a person such as the object P). For this reason,
it is desirable that the imaging apparatus 12 acts not according to
operations performed by the operator O but according to operations
performed by the medical engineer M in the inspection room.
[0038] Thus, in the present embodiment, the imaging apparatus 12
acts not according to operations performed by the operator O but
according to operations performed by the medical engineer M in the
inspection room. Not the medical engineer M but the operator O
actually performs medical treatment while confirming X-ray images.
Hence, in order to acquire X-ray images desired by the operator O
of the device 32, it is required that the medical engineer M
adjusts positional relationship between the imaging system and the
bed 16 of the imaging apparatus 12.
[0039] For the above reason, the X-ray diagnostic apparatus 11 of
the present embodiment acquires information on an imaging region
and an imaging direction of desirable X-ray images from the
operator O of the device 32 via the remote input circuit 43 of the
remote console 40 or an input circuit 72 of the image processing
apparatus 20 in the operators room. The desirable X-ray images are
the images that operator O desires to observe during the medical
treatment. Hereinafter, an imaging region and an imaging direction
of desired X-ray images in the above description are referred to as
a desired region and a desired direction, respectively. Then, the
X-ray diagnostic apparatus 11 provides the medical engineer M with
a provisional image for positioning (hereinafter, referred to as a
positioning provisional image) which is appropriate for assistance
in positioning of the imaging apparatus 12 performed by the medical
engineer M, according to the desired region and the desired
direction. At the same time, the X-ray diagnostic system 11
provides the operator O with a provisional image for medical
treatment (hereinafter, referred to as an operative provisional
image) which is appropriate for assistance in medical treatment
performed by the operator O of the device 32, according to the
desired region and the desired direction.
[0040] The remote console 40 includes display input circuits 41 and
42, a remote input circuit 43 for remotely controlling the device
32 of the remote catheter 30, and a controller 44.
[0041] Each of the display input circuits 41 and 42 includes a
display and a touch sensor provided in the vicinity of this
display. The display is configured of a general display output
device such as a liquid-crystal display and an OLED display. The
touch sensor outputs information on an instruction position on the
touch sensor pointed by a user to processing circuitry of the
controller 44. When the touch sensor is configured of, e.g., an
electrostatic capacity panel of a projection type, the touch sensor
has electrode rows arranged vertically and horizontally. In this
case, the touch sensor can acquire a contact position based on
output change of the electrode row according to change in
electrostatic capacity in the vicinity of the contact position of a
contact object.
[0042] The display of the display input circuit 41 is controlled by
the processing circuitry of the controller 44 and displays, e.g.,
an image similar to that on the display 18. When the operator O of
the device 32 inputs information for setting the desired region and
the desired direction into the controller 44 via the remote input
circuit 43, the display of the display input circuit 41 displays an
operative provisional image.
[0043] The display of the display input circuit 42 is controlled by
the processing circuitry of the controller 44 and displays, e.g.,
information on a control target device of the remote input circuit
43. Additionally, the display of the display input circuit 42 may
display an operative provisional image when the operator O of the
device 32 inputs information for setting the desired region and the
desired direction into the controller 44 via the remote input
circuit 43.
[0044] The remote input circuit 43 includes a hand switch for
instructing an X-ray exposure timing and a general pointing device
such as a track ball, a track ball mouse, a keyboard, a touch
panel, a ten-key, a voice input circuit, and eye-gaze input
circuit. The remote input circuit 43 outputs a signal for remotely
controlling the device 32 to the remote catheter 30 via the
controller 44 by wire or wirelessly, when being operated by the
operator O.
[0045] Moreover, the remote input circuit 43 provides the
controller 44 with information for setting the desired region and
the desired direction of a desirable X-ray image which the operator
O of the device 32 uses during manipulation of medical treatment,
when being operated by the operator O.
[0046] The controller 44 includes at least a processor and memory
circuitry. The processing circuitry of the controller 44 is linked
with the image processing apparatus 20 according to programs stored
in this memory circuitry. For instance, the processing circuitry of
the controller 44 outputs information on feed movement amount of
the device 32 to the image processing apparatus 20. Additionally,
the processing circuitry of the controller 44 provides the image
processing apparatus 20 with information for setting the desired
region and the desired direction inputted by the operator O via the
remote input circuit 43.
[0047] Further, the remote console 40 may be provided with a
speaker and a microphone which enable the operator O of the remote
console 43 and the medical engineer M to communicate with each
other in real time by phone, for instance.
[0048] FIG. 2 is a block diagram illustrating configuration of the
inspection room console 19. The inspection room console 19 includes
a display 51, an input circuit 52, memory circuitry 53, a
communication circuit 54, a speaker 55, a microphone 56, and
processing circuitry 57.
[0049] The display 51 is configured of a general display output
device such as a liquid-crystal display and an OLED display, and
displays various types of information such as a positioning
provisional image and a fluoroscopic image to be updated on a
real-time basis under the control of the processing circuitry 57.
The input circuit 52 is configured of a general display device such
as a keyboard, a touch panel, a track ball, a ten-key, a voice
input circuit, a visual line input circuit, and outputs an input
signal corresponding to an operation by the medical engineer M to
the processing circuitry 57.
[0050] The memory circuitry 53 is equipped with configuration
including a recording medium which can be read by the processor
such as a magnetic or optical recording medium and/or a
semiconductor memory. The memory circuitry 53 may be configured
such that some or all of those programs and data in the recording
medium are downloaded through an electronic network. The memory
circuitry 53 previously or preliminarily stores three-dimensional
medical image data of a human body diagram in imitation of a human
body (hereinafter, referred to as 3D model data) as an example of
medical data. Additionally, the memory circuitry 53 may previously
store three-dimensional medical image data (hereinafter, referred
to as volume data) of the object P which are acquired in advance.
Hereinafter, 3D model data and volume data are collectively
referred to as 3D data.
[0051] As to medical data, it is enough that medical data are data
available for setting an imaging region and an imaging direction of
an X-ray image which the operator O desires to refer to while
performing manipulation with the use of the device 32. For
instance, medical data may be two-dimensional medical image data, a
list of anatomical data of, e.g., character strings indicating
anatomical landmark, or combination of both. The operator O
designates a position on medical data via the designation receiving
circuit. The X-ray diagnostic system 1 causes the first display
such as the display of the display input circuit 41 or 42 to
display the first image according to the designated position, and
causes the second display such as the display 18 to display the
second image according to the designated position. Note that the
second image is different from the first image.
[0052] Additionally, medical data may be prepared for each type of
classification such as classification based on age of the object P
including an adult and a child, classification based on gender, and
classification based on body weight. In this case, the operator O
may preferably select one set of medical data in consideration of
the classification to which the object P belongs so as to instruct
a position on the selected medical data.
[0053] In the present embodiment, a description will be given of a
case where medical data are 3D data.
[0054] The communication circuit 54 implements various types of
information communication protocols according to aspects of
networks. The communication circuit 54 connects the inspection room
console 19 with the controller 44 of the image processing apparatus
20 and the remote console 40 according to the various types of
information communication protocols. In this connection, e.g.,
electric connection via electronic network can be applied. The
electronic network means general information communication network
using telecommunications technology and includes, e.g., a telephone
communication network, an optical fiber communication network, a
cable communication network, and a satellite communication network
in addition to a wireless/wired LAN (Local Area Network) and the
Internet network. For instance, the processing circuitry 57 may
acquire volume data of the object P from, e.g., an image server via
a network and store the acquired data in the memory circuitry
53.
[0055] The speaker 55 and the microphone 56 are used, e.g., when
the operator O of the image processing apparatus 20 in the
operators room and the medical engineer M communicate with each
other by phone or by video call in real time through voice
information communication performed by the communication circuit
54. Additionally, the speaker 55 and the microphone 56 are used
when the operator O of the remote console 40 in the operators room
and the medical engineer M communicate with each other by phone or
by video call in real time through voice information communication
performed by the communication circuit 54.
[0056] The processing circuitry 57 is a processor configured to
perform processing of assisting the medical engineer M in adjusting
an imaging region and an imaging direction in cooperation with the
processing circuitry 77 of the image processing apparatus 20 by
reading out and executing programs stored in the memory circuitry
53 such that X-ray images desired by the operator O of the device
32 are acquired.
[0057] As shown in FIG. 2, the processing circuitry 57 implements a
determined image acquisition function 61, a positioning provisional
image generation function 62, a fluoroscopic image acquisition
function 63, and a communication function 64. Those functions 61 to
64 are stored in the memory circuitry 53 in the form of
programs.
[0058] Incidentally, the positioning provisional image generation
function 62 may be implemented by the processing circuitry 77 of
the image processing apparatus 20. In this case, the positioning
provisional image generation function 62 may be omitted from the
processing circuitry 57.
[0059] FIG. 3 is a block diagram illustrating configuration of the
image processing apparatus 20.
[0060] The image processing apparatus 20 includes a display 71, an
input circuit 72, memory circuitry 73, a communication circuit 74,
a speaker 75, a microphone 76, and processing circuitry 77.
[0061] The display 71 is configured of a general display output
device such as a liquid-crystal display and an OLED display, and
displays various type of information such as medical images under
the control of the processing circuitry 77. Additionally, when the
operator O of the device 32 provides the processing circuitry 77
with information for setting the desired region and the desired
direction via the input circuit 72, the display 71 displays an
operative provisional image.
[0062] The input circuit 72 is configured of, e.g., a general input
device such as a keyboard, a touch panel, a track ball, a ten-key,
a voice input circuit, and a visual line input circuit. The input
circuit 72 outputs an input signal, which is in accordance with an
operation performed by a user in the operators room including the
medical engineer M and the operator O, to the processing circuitry
77. Additionally, when being operated by the operator O, the input
circuit 72 provides the processing circuitry 77 with information
for setting the desired region and the desired direction of an
X-ray image which the operator O desires to refer to during
manipulation with the use of the device 32.
[0063] The memory circuitry 73 is equipped with configuration
including a recording medium which can be read by the processor
such as a magnetic or optical recording medium and/or a
semiconductor memory. The memory circuitry 73 may be configured
such that some or all of those programs and data in the recording
medium are downloaded through an electronic network. Additionally,
the memory circuitry 73 previously or preliminarily stores 3D model
data of a human body diagram in imitation of a human body as an
example of medical data. Further, the memory circuitry 73 may
previously store volume data of the object P which are acquired in
advance.
[0064] The communication circuit 74 implements various types of
information communication protocols according to aspects of
networks. The communication circuit 74 connects the image
processing apparatus 20 with the controller 44 of the inspection
room console 19 and the remote console 40 according to the various
types of information communication protocols. In this connection,
e.g., electric connection via an electronic network can be applied.
For instance, the processing circuitry 57 may acquire volume data
of the object P from, e.g., an image server via a network so as to
store the acquired volume data in the memory circuitry 53.
[0065] For instance, the speaker 75 and the microphone 76 are used
when the operator O of the image processing apparatus 20 in the
operators room and the medical engineer M communicate with each
other by phone or by video call in real time through the
communication circuit 74.
[0066] The processing circuitry 77 is a processor configured to
perform processing of assisting the medical engineer M in adjusting
an imaging region and an imaging direction in cooperation with the
processing circuitry 57 of the inspection room console 19 by
reading out and executing programs stored in the memory circuitry
73 such that X-ray images desired by the operator O of the device
32 are acquired.
[0067] As shown in FIG. 3, the processing circuitry 77 implements a
selection receiving function 81, an image determination function
82, an operative provisional image generation function 83, a
positioning provisional image generation function 84, and a
communication function 85. Those functions 81 to 85 are stored in
the memory circuitry 73 in the form of programs.
[0068] The positioning provisional image generation function 84 may
be implemented by the processing circuitry 57 of the inspection
room console 19. In this case, the positioning provisional image
generation function 84 may be omitted from the processing circuitry
77. Additionally, when the operator O of the device 32 provides the
controller 44 with information for setting the desired region and
the desired direction via the remote input circuit 43 of the remote
console 40, those functions 81 to 85 of the processing circuitry 77
of the image processing apparatus 20 may be implemented by the
controller 44 of the remote console 40, instead of the processing
circuitry 77.
[0069] Next, one of operations performed by the X-ray diagnostic
system 1 and the medical image diagnostic system 10 of the present
embodiment will be described as an example. First, brief overview
of the operation of the X-ray diagnostic system 1 and the medical
image diagnostic system 10 will be described.
[0070] FIG. 4 is a flowchart illustrating processing of assisting
the medical engineer M in adjusting an imaging region and an
imaging direction such that X-ray images desired by the operator O
of the device 32 are acquired.
[0071] In FIG. 4, each reference sign composed of S and number on
its right side indicates step number of the flowchart.
[0072] In the step S1, the X-ray diagnostic apparatus 11 receives s
selected single 3D data out of plural 3D model data and volume data
of the object P from the operator O via the input circuit 72, the
remote input circuit 43, or the touch sensor of the input circuit
41 or 42, and then causes the display disposed at a position
visible from the operator O to display the selected 3D data. Note
that the above plural 3D model data are examples of medical data,
and the input circuit 72, the remote input circuit 43, and the
touch sensor of the input circuit 41 or 42 are examples of the
designation receiving circuit.
[0073] In the next step S2, the operator O rotates, magnifies, or
reduces the selected 3D data by operating the input circuit 72 or
the remote input circuit 43 while confirming the selected 3D data.
In this manner, the operator O causes the display disposed at a
position visible from the operator O to display a part of the 3D
data corresponding to an imaging region and an imaging direction of
an X-ray image which the operator O desires to refer to during
manipulation. The X-ray diagnostic apparatus 11 determines a
partial image corresponding to the desired region and the desired
direction of the selected 3D data (i.e., the imaging region and the
imaging direction of the X-ray image which the operator O desires
to refer to during manipulation) as a provisional image, according
to an operation of the operator O with respect to the selected
three-dimensional data.
[0074] In the step S3, the X-ray diagnostic apparatus 11 generates
an operative image based on the provisional image, and causes the
display disposed at a position visible from the operator O to
display the operative image. Additionally, the X-ray diagnostic
apparatus 11 generates a positioning provisional image based on the
provisional image, and causes the display disposed at a position
visible from the medical engineer M to display the positioning
provisional image. Incidentally, the input circuit 72 or the remote
input circuit 43 may receive only a designation of size on 3D data.
In this case, the operative provisional image generation function
83 generates the operative provisional image 91 in accordance with
the designated size, and causes the display 71 to display the
generated operative provisional image 91.
[0075] Next, details of the operation of the X-ray diagnostic
system 1 and the medical image diagnostic system 10 will be
described with reference to FIG. 5 to FIG. 9.
[0076] FIG. 5 is a flowchart illustrating details of the flow of
processing shown in FIG. 4. In FIG. 5, each reference sign composed
of S and number on its right side indicates step number of the
flowchart. FIG. 6 is a schematic diagram illustrating 3D data to be
selected. FIG. 7 is a schematic diagram illustrating how the
desired region and the desired direction are set to selected 3D
data. FIG. 8 is a schematic diagram illustrating the operative
provisional image 91 generated on the basis of the provisional
image. FIG. 9 is a schematic diagram illustrating a positioning
provisional image 92 generated on the basis of the provisional
image.
[0077] Incidentally FIG. 5 illustrates a case where the operator O
of the device 32 provides the processing circuitry 77 with
information for setting the desired region and the desired
direction via the input circuit 72 of the image processing
apparatus 20 as an example of the designation receiving
circuit.
[0078] First, in the step S11, the selection receiving function 81
of the image processing apparatus 20 causes the display 71 disposed
at a position visible from the operator O to display an image based
on the volume data of the object P and respective images indicated
by plural 3D model data. Those plural 3D model data are examples of
medical data stored in the memory circuitry 73. Note that images to
be displayed in the processing shown in FIG. 5 may be displayed on
the display(s) of at least one of the display input circuits 41 and
42. Additionally, the selection receiving function 81 receives
input for selecting one of the volume data of the object P and
plural 3D model data from the operator O via the input circuit 72,
and causes the display 71 to display the image indicated by the
selected 3D data (FIG. 6).
[0079] In the next step S12, while confirming the selected 3D data,
the operator O moves, rotates, magnifies, or reduces the selected
3D data by operating the input circuit 72 so as to cause the
display 71 to display a part of the selected 3D data corresponding
to the imaging region and the imaging direction of the X-ray image
which the operator O desires to refer to during manipulation. The
image determination function 82 determines the partial image
corresponding to the desired region and the desired direction of
the selected 3D data (i.e., the imaging region and the imaging
direction of the X-ray image which the operator O desires to refer
to during manipulation) as the provisional image, according to an
operation performed by the operator O with respect to the selected
3D data (FIG. 7).
[0080] When the operator O instructs a certain region as the
desired imaging region, the image determination function 82 may
determine the provisional image by setting the desired region such
that at least the instructed region is included in the desired
region. Additionally, when the operator O instructs a predetermined
position as the desired imaging region, the image determination
function 82 may determine the provisional image by setting the
desired region such that at least a predetermined range centered on
the instructed position is included in the desired region.
[0081] In the next step S13, the operative provisional image
generation function 83 generates the operative provisional image 91
based on the provisional image so as to cause the display 71 to
display the operative provisional image 91. Specifically, as the
operative provisional image 91, the operative provisional image
generation function 83 generates an image including at least an
image, which corresponds to a tubular structure (e.g., a blood
vessel) attracting the attention of the operator O during
manipulation and is an image observed from the same direction as
the desired direction of the provisional image, on the basis of
provisional image (FIG. 8). In this case, the operative provisional
image 91 may be generated by applying image processing in which
blood vessels are emphasized. Preferably, the operative provisional
image 91 is such an image that a position of a therapeutic target
portion is recognizable or distinguishable for the operator O.
[0082] Although it may be preferable that the operative provisional
image 91 looks like an image obtained by fluoroscopy or radiography
by performing image processing on 3D data (e.g., selected 3D data),
an image obtained by performing rendering processing such as volume
rendering on 3D data (e.g., selected 3D data) may also be used for
the operative provisional image 91. Additionally, the operative
provisional image 91 may be a gray-scale image, a color image
including chromatic colors, or an image in which only target
tubular structures are colored on the basis of a gray-scale
image.
[0083] In the next step S14, the operative provisional image
generation function 83 determines whether the operative provisional
image 91 is an image desired by the operator O or not, according to
an instruction inputted by the operator O via the input circuit 72.
When the operative provisional image 91 is an image desired by the
operator O, the provisional image which is the original image of
this operative provisional image 91 determined to be an image
desired by the operator O is inputted to the positioning
provisional image generation function 84 or the determined image
acquisition function 61 of the inspection room console 19, and the
processing proceeds to the step S15.
[0084] Conversely, when the operative provisional image 91 is not
satisfactory for the operator O, the processing returns to the step
S12 and a series of processing from the steps S12 to S14 is
repeated again. In other words, setting of a provisional image
(i.e., setting of a desired region and a desired direction) is
performed again, then a provisional image is redetermined in the
step S12, then the operative provisional image is regenerated in
the step S13, and then the processing proceeds to the step S14
again. In this manner, the operator O can use the operative
provisional image 91 for determining the provisional image.
[0085] Next, in the step S15, the positioning provisional image
generation function 84 of the image processing apparatus 20 or the
positioning provisional image generation function 62 of the
inspection room console 19 generates the positioning provisional
image 92 based on the provisional image, and causes the display 18
disposed at a position visible from the medical engineer M to
display the generated positioning provisional image 92. In a series
of processing shown in FIG. 5, images to be displayed on the
display 18 may also be displayed on the display 51.
[0086] Specifically, the positioning provisional image generation
function 84 or 62 may generate an image satisfying the following
first and second conditions as the positioning provisional image 92
based on the provisional image (FIG. 9). The first condition is
that the image is viewed from the same direction as the desired
direction of the provisional image, and the second condition is to
be appropriate for being referred to by the medical engineer M when
positioning of at least one of the imaging system and the bed 16 is
performed such that X-ray imaging is performed on a region
including the desired region in the desired direction.
[0087] Although it may be preferable that the positioning
provisional image 92 looks like an image obtained by fluoroscopy or
radiography by performing image processing on 3D data (e.g.,
selected 3D data) as well as the operative provisional image 91, an
image obtained by performing rendering processing such as volume
rendering on 3D data (e.g., selected 3D data) may also be used for
the positioning provisional image 92. In other words, the
positioning provisional image 92 may be generated by applying image
processing which is different from the image processing used for
generating the operative provisional image 91.
[0088] Additionally, the positioning provisional image 92 may be
such an image that distinguishably depicts a part corresponding to
the operative provisional image 91. In this case, for instance, a
sign or a character string indicative of a part corresponding to
the operative provisional image 91 and/or a frame border or a
graphic indicative of the range of the operative provisional image
91 may be superimposed on the positioning provisional image 92.
[0089] Additionally, the positioning provisional image 92 may be
generated in such a manner that the center of the positioning
provisional image 92 matches the center of the operative
provisional image 91.
[0090] Further, it may be preferable that the positioning
provisional image 92 is generated so as to include an image of a
bone which has a high X-ray absorption coefficient and is easily
recognized in a fluoroscopic image. In this case, the positioning
provisional image 92 may be generated by applying image processing
in which bones are emphasized. As to generation of the positioning
provisional image 92, an image part of a tubular structure such as
a blood vessel included in the operative provisional image 91 may
be superimposed on the positioning provisional image 92 (two-dot
chain line in 92 of FIG. 9), and the positioning provisional image
92 may be generated so as not to include a blood vessel. When 3D
data being the original image of the provisional image are past
volume data of the object P and a portion with a high X-ray
absorption coefficient such as a stent is placed inside the object
P, the positioning provisional image 92 may be generated so as to
include such type of portion. Additionally, it may be preferable
that the positioning provisional image 92 is generated as an image
of a wider field of view than the operative provisional image 91.
This is so that the positioning provisional image 92 can be easily
used for adjusting positional relationship between the imaging
system and the bed 16.
[0091] Moreover, the positioning provisional image generation
function 84 or 62 may generate an angle-information image 92a
indicative of an angle of the X-ray irradiation axis of the imaging
system with respect to the bed 16 on the basis of information on
the desired direction of the determined provisional image so as to
cause the display 18 to display the angle-information image 92a
(FIG. 9). At the timing when the provisional image is determined
and the desired direction is determined, the angle of the X-ray
irradiation axis of the imaging system with respect to the bed 16
can be determined. Note that since there are various positional
relationships between the bed 16 and the object P, it is difficult
to determine the X-ray irradiation position. However, by proposing
the angle of the X-ray irradiation axis of the imaging system with
respect to the bed 16 and the angle-information image 92a
indicative of the irradiation direction, it is possible to assist
the medical engineer M in performing positioning of at least one of
the imaging system and the bed 16 such that X-ray imaging is
performed on a region including the desired region in the desired
direction. The angle-information image 92a may be an image in
imitation of the imaging system and the bed 16 like FIG. 9, texture
information indicative of the angle of the X-ray irradiation axis
of the imaging system with respect to the bed 16, or combination of
both.
[0092] The medical engineer M roughly adjusts positional
relationship between the imaging system and the bed 16 based on the
positioning provisional image 92 and the angle-information image
92a displayed on the display 18 by the positioning provisional
image generation function 84 or 62, without irradiating the object
P with X-rays.
[0093] In the next step S16, according to an instruction of the
medical engineer M via the input circuit 52, the fluoroscopic image
acquisition function 63 acquires fluoroscopic images generated on
the basis of X-ray imaging of the object P performed by the imaging
apparatus 12 in real-time.
[0094] In the next step S17, the positioning provisional image
generation function 84 or 62 causes the display 18 to display the
positioning provisional image 92 and the updated fluoroscopic image
acquired on a real-time basis in parallel, in such a manner that
the medical engineer M can compare the positioning provisional
image 92 with the updated fluoroscopic image. The medical engineer
M finely adjusts the positional relationship between the imaging
system and the bed 16, while comparing the positioning provisional
image 92 with the updated fluoroscopic image acquired on a
real-time basis.
[0095] In the next step S18, the operator O determines whether the
current fluoroscopic image is sufficient and desirable for
performing manipulation. When it is determined to be sufficient and
desirable, the operator O provides the fluoroscopic image
acquisition function 63 with information indicative of that via the
input circuit 72 so as to stop X-ray irradiation, and thereby a
series of processing is completed. As a result, the positional
relationship between the imaging system and the bed 16 of the
imaging apparatus 12 becomes such relationship that the operator O
can acquire desired X-ray images with operational help of the
medical engineer M.
[0096] Conversely, when the operator O determines that the current
fluoroscopic image is not sufficient or desirable, in the step S19,
the operator O requests the medical engineer M to readjust the
positional relationship between the imaging system and the bed 16
of the imaging apparatus 12, and the medical engineer M acquires
detailed instructions for readjusting the positional relationship.
The methods of informing the detailed instructions for readjustment
via the communication function 85 of the image processing apparatus
20 and communication function 64 of the inspection room console 19
include telephone, videotelephone, transmission/reception of
e-mails, and chat and the like. When the instruction from the
operator O is received the processing returns to the step S16, and
the positional relationship between the imaging system and the bed
16 is readjusted.
[0097] In the above-described manner, it is possible to assist the
medical engineer M in adjusting the imaging region and the imaging
direction such that X-ray images desired by the operator O of the
device 32 are acquired.
[0098] The X-ray diagnostic apparatus 11 of the present embodiment
can present the operator O with the operative provisional image 91
appropriate for manipulation based on the desired region and the
desired direction determined by the operator (FIG. 8), and can
present the medical engineer M with the positioning provisional
image 92 appropriate for adjusting the positional relationship
between the imaging system and the bed 16 (FIG. 9). Thus, according
to the X-ray diagnostic apparatus 11, the medical engineer M in the
inspection room can easily and accurately adjust the positional
relationship between the imaging system and the bed 16 such that
images deserted by the operator O of the device 32 are
acquired.
[0099] Additionally, the X-ray diagnostic apparatus 11 can generate
the angle-information image 92a indicating the angle of the X-ray
irradiation axis of the imaging system with respect to the bed 16
based on the desired direction determined by the operator O so as
to cause the display 18 to display the angle-information image 92a
(FIG. 9). Thus, the medical engineer M can adjust the positional
relationship between the imaging system and the bed 16 more
quickly.
[0100] Further, according to a series of processing shown in FIG.
5, after roughly adjusting the positional relationship between the
imaging system and the bed 16 without irradiating the object P with
X-rays, the positional relationship can be finely adjusted by using
fluoroscopic images. Thus, X-ray exposure of the object P during
adjustment of the positional relationship can be drastically
reduced.
[0101] Incidentally, the communication circuit 54 of the present
embodiment is an example of the communication circuit recited in
the claim.
[0102] The processing circuitry 57, 77 and processing circuitry of
the controller 44 of the remote console 40 in the present
embodiment are examples of processing circuitry recited in the
claims.
[0103] The input circuit 72, the respective touch sensors of the
display input circuit 41 and 42, and the remote input circuit 43 in
the present embodiment are examples of the designation receiving
circuit recited in the claims.
[0104] The respective touch sensors of the display input circuits
41 and 42 and the remote input circuit 43 in the present embodiment
are examples of the operation circuit recited in the claim.
[0105] The respective displays of the display input circuits 41 and
42 of the remote console 40 and the display 71 of the image
processing apparatus 20 in the present embodiment are examples of
the first display recited in the claims.
[0106] The display 18 of the inspection room in the present
embodiment is an example of the second display recited in the
claims.
[0107] The term "processor" used in the processing circuitry 57, 77
of the image processing apparatus 20 and the processing circuitry
of the controller 44 of the remote console 40 in the
above-described embodiments, for instance, refer to circuitry such
as dedicated or general purpose CPUs (Central Processing Units),
dedicated or general-purpose GPUs (Graphics Processing Units), or
ASICs (Application Specific Integrated Circuits), programmable
logic devices including SPLDs (Simple Programmable Logic Devices),
CPLDs (Complex Programmable Logic Devices), and FPGAs (Field
Programmable Gate Arrays), and the like. The processor implements
various types of functions by reading out and executing programs
stored in the memory circuitry.
[0108] In addition, instead of storing programs in the memory
circuitry, the programs may be directly incorporated into the
circuitry of the processor. In this case, the processor implements
each function by reading out and executing each program
incorporated in its own circuitry. Moreover, although FIG. 2 and
FIG. 3 show an example in which the processing circuitry configured
of a single processor implements respective functions, the
processing circuitry may be configured by combining plural
processors independent of each other such that each processor
implements each function of the processing circuitry by executing
corresponding program. When plural processors are provided for the
processing circuitry, memory circuitry for storing programs may be
individually provided for each processor, or one memory circuitry
may collectively store programs corresponding to all the functions
of the processors.
[0109] While certain embodiments have been described, these
embodiments have been presented by way of example only, and are not
intended to limit the scope of the inventions. Indeed, the novel
embodiments described herein may be embodied in a variety of other
forms; furthermore, various omissions, substitutions and changes in
the form of the embodiments described herein may be made without
departing from the spirit of the inventions. The accompanying
claims and their equivalents are intended to cover such forms or
modifications as would fall within the scope and spirit of the
inventions.
[0110] For instance, an X-ray CT (Computed Tomography) apparatus
capable of CTF (Computed Tomography Fluoroscopy) may be used
instead of the X-ray diagnostic apparatus 11 of the present
embodiment.
[0111] Moreover, in the embodiments of the present invention,
although an example of processing in which each step of a flowchart
is executed along a time series according to the described order
has been shown, the processing may not necessarily be performed
along the time series, and may be performed in parallel or
individually.
